If you want to animate the motion/ rotation, you need to re-write parts of the script,...
Cause now you are creating a completly different scenario,...
With animated motion, people mite accidently click a moving/ rotating shape and mess up the coordinates/ rotation
so you would need to build in a few conditionals to prevent users from doing that.
I'm out of town atm and don't have swish at hand,.. but I'll have a look at it when I get back.
just a tip: its always best to have the most complete scenario how things should work, before you start scripting,
cause small changes in the scenario often mean a lot of changing in the script/ scriptstructure.
